Hello Oleg!
First of all I think you have some good content. With that being said, I'll be giving you advice as if you were applying for a level design position:
For starters, you seem to go into great detail about your development process for only two of your pieces (The Roots and Enemy's Lair). Ideally you should be doing this for all of your content, unless there are restrictions. This helps me figure out different aspects of your level design like how your level uses the game's mechanics in interesting ways or how you've solved problems within your gameplay space.
I'd also recommend only posting content that is relevant to your title. In your Valley of Heroes entry, you have character models displayed at the bottom. You're not a character modeler, nor am I going to hire you for that role since you're not specialized in it. I want to hire you as a level designer, show me levels and design documents.
Lastly a bug:
- The 'day to day' link in your Roots page points to a page that no longer exists
Hope this helps!
